Abstract

A circuit is provided for generating a modulated laser diode control signal from a laser diode control signal, the circuit having an RF modulator for modulating the laser diode control signal with a modulation signal; the circuit having adjustment means for adjusting the RF modulator; the adjustment means being configured or configurable as a function of at least one laser diode operating information item. Furthermore, a laser diode receptacle is described as having such a circuit, a projector, particularly an image projector having such a laser diode receptacle, an image projector having such a laser diode receptacle and a laser diode, as well as a method for adjusting an RF modulator of such a circuit and a method for producing such a laser diode receptacle.
